-AxLl-z-LuBRICATOR.

SPECIFICATION forming part Of Letters Patent N0. 680,388, dated August13, 1901.

Application tiled August 25, 1900. Serial No. 28,054. (No model.)

To @ZZ whom t may concern:

Be itknown that I, THOMAS HENRY McCAU- LEY, a subject of the Queen ofGreat Britain, residing at Port Arthur, in the Province of Ontario andDominion ofOanada, have invented a new and useful Oar-Axle Lubricator,of which the following is a specification.

My invention is an improved car-axle lubricator, one object of myinvention being to l provide a resilient oil-absorbing packing materialwhich by its elasticity will keep in contact with the spindle of thecar-axle and supply the same with lubricant from the axle-box.

A further object of my inventionis to provide means for keeping thepacking material in place in the car-axle box and to permit the readyinsertion of said packing material therein and its removal therefrom.

My invention consists in the peculiar construction and combination ofdevices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical longitudinalsectional View of a caraxle box provided with a closure and a packingmaterial embodying my invention. Fig. 2 is a detail perspective View,partly in seetion, of my improved car-axle-box packing. Fig. 3 is asimilar view of the same.

The axlebox 1 has its outer end open. The bearing-surface 3 in the upperside-of the axle-box is of the usual construction and bears upon theupper side of the spindle 4 of the caraxle 5. A removable closure 6 isplaced in the front end of the car-axle box and bears against the outerend of the spindle of the car-axle. The said closure is adapted to beinserted and removed through the opening 2 and is of suitable form toenable it to it snugly in the front end of the car-axle box, as shown,and is disposed at the outer end of the axle-spindle. Preferably thesaid removable closure is hollow and is weighted in its lower side, asat 7. The said closure serves to keep the packing 8 in place in thelower side of the car-axle box under the spindle of the axle andprevents the packing from being displaced and crawling out beyond theend of the axle-spindle, and the bottom of the closure is perforated toadmit oil to the packing.

The hollow form of the closure adapts it to form a reservoir to hold theoil placed vpieces of suitable oil-absorbing material 10,

which pieces may be made of felt or'other suitable substance. Thereby alength of packing is formed, as shown in Fig. 2, and the relativedimensions of the said packing material and the said wire core are suchthat the said length of packing may be bent and doubled upon itself, asshown in Fig. 3, While being crowded into the car-axle box and disposedin such shape as to entirely ll the lower side of the car-axle box, asshown in Fig. l. The said wire 9, which forms the core of the axle-boxpacking, is a spring-wire, the inherent elasticity of which, Whilepermitting of the doubling and bending of the packing as the same isplaced in the car-axle box, serves to keep the packing alive and incontact with the lower side of the axle-spindle and prevent the samefrom settling in the lower side of the car-axle box andreceding from theaxle-spindle. The said packing becomes saturated with the oil or otherlubricant in the car-axle box and serves-to apply the same to thespindle of the axle as the same is needed as long as any of the oilremains in the box. Hence the box and axlespindle are prevented fromheating, as will be understood.

I do not desire to limit myself to the precise construction of thepacking hereinbefore described, as the same may be modified Within thescope of my invention.

Any suitable absorbent material may be substituted for the felt, and theabsorbent material may be Woven on the wire or secured between two wiresby twisting the latter together. Any suitable kind of cloth having oneor more spring wires disposed therein may be also employed. Othermodifications may also may be made.

Having thus described my invention, I claiml. A car-axle-box packingcomprising a IOO length of elastic packing material capable of absorbingoil and a longitudinally-disposed stiifening-core, as a wire in the saidlength of packing material, the relative dimensions of said core andpacking material thereon being such as to adapt the said packing to bebent and doubled upon itself and crowded in a mass into-a car-axle boxso as to bear against the journal of the axle, substantially asdescribed.

2. An elastic car-axle-box packing comprising a length of Wire forming acore and pieces of absorbent material strung on the said core, therelative dimensions'of said core and said packing material being such asto adapt said packing to be bent and doubled upon itself and crowdedinto car-axle box so as to bear against the journal of the axle,substantially as described.

3. An elastic car-axle-box packing comprising a length of spring\vireforming a core and pieces of absorbent material strung on the said wire,the relative dimensions of said core and said packing material beingsuch as to adapt the said packing to be bent and doubled npon itself andcrowded into a car-axle box so as to bear against the journal of theaxle, substantially as described.

4. A car-axle box having a removable closure in its outer end, andbearing against the outer end of the axle-spindle, said closure beingadapted to bear against packing material in the said car-axle box andprevent said material from being displaced from under said spindle,substantially as described.

5. A car-axle box having a removable closure in its outer end, andbearing against the outer end of ythe axle-spindle, said closure beingadapted to bear against packing material in the said car-axle box andprevent said material from being displaced from under said spindle, saidclosure forming an oil-receptacle and being perforated to feed oil tothe packing, substantially as described.

In testimony that I claim the foregoing as my oWn I have hereto affixedmy signature in the presence of two Witnesses.
